Hi @syninno. Thanks for being part of GoDaddy Community! It's difficult to say for sure what's happening in your situation without more information. If you're still having trouble, I suggest reviewing the post here to learn more about what kind of information you can supply to help others offer good responses. Hope you're able to get this figured out!
Thank you very much for your reply.
Will provide more information below:
Thanks @syninno. It looks like there are no DNS entries for cshcc.syninno.com (or syninno.com for that matter). If you are using this subdomain in a local network, then there may be an issue with the certificate on the network. For that, you'd need to reach out to your network administrator. This 3rd party article may help.
If you intend for cshcc.syninno.com to be accessible from the internet, then you'll want to check with your DNS provider to see if you need to make changes on their end to make the DNS live.
